Diamond Fluorescence is checked by using a ultraviolet light (UV). The ultraviolet light emits the diamonds light when placing the diamond under the ultraviolet (UV) light. In a lab setting, This ultraviolet lighting is reported as medium, strong and very strong. Grading a diamond and differencing a non fluorescence or a fluorescence diamond that emits light that is white, yellow or another color depending on the diamond.
How does a diamonds fluorescence effect the quality of a diamond?
The fluorescence does not effect the appearance or quality from a diamond with fluorescence and a diamond without fluorescence. The Cut of the diamond has a lot to do with fluorescence refraction from a diamonds light spectrum.
Where Can i Find info on Fluorescence Diamonds?
You can find UV light info on your GIA, AGS, IGI diamond certificate.
